I am so sorry you have contracted this disease. I know it is difficult and try to prevent is always, as I am prescribed antibiotics often. I use FlorastoreOTC during and following antibiotic Rx. So far so good. It might be worth a try. I also drink a small amount of Kefir that can be found in the yogurt section of your grocery store. Both of these are helpful. This is a disease that has had successful intervention. I hope this disease can be abated for you. I would seek a specialist if these products do not help. A dietitian/ website can list foods to avoid. I wish you well and God speed in this endeavor.
